structure of battery: A
chamber of lead acid battery is composed by Lead, Lead Oxide, sulfuric acid
The Lead and Lead Oxide plate are so called electrode. Positive electrode is Lead plate. Negative electrode is Lead
Oxide plate. There are several chambers to connecting together to be a battery.
discharge work: When
battery discharging, The lead in negative plate will react with ion in sulfuric
This composite will toward positive electrode in the solution and releasing electron in the negative electrode. The releasing
electron will follow the wire loop back to positive electrode. The releasing electron is so called "current". In positive electrode,
PbO2, H+, and SO42- react to PbSO4 and water.
charge work: When charging,
the positive and negative electrodes connect to direct current. The inside
reverse to discharging mechanism. The materials in battery will return to its original state.
In the reaction stated previously will produce some "sulfation"(PbSO4).In theory, the sulfation should 100% return to its original
state(Pb, PbO2, SO42-) when charging. Unfortunate, part of sulfation is irreversible. And will gradually accumulate on the electrodes.
This irreversible crystalline will isolate the electrode react with the sulfuric acid solution. Make the chemical reaction difficult.
Finally, the battery loses its charging and discharging ability.
There are many reasons to premature Battery Failure
1. The battery is over discharged and without charging in time.
2. The quantity of sulfuric acid solution is not enough. Or inadequately supply water or sulfuric acid.
3. Your car or boat did not operate in a long period. And did not unload the battery from electric loop. The battery will steady
discharge in the electric loop naturally.
The sulfation will make the impedance increasing for two electrode reaction. The PbSO4 crystalline can't return to its original
materials. The voltages decline too quickly when discharging. The voltage increase too quickly when charging. The density of
electrolyte can't stay in normal range . The efficiency of charging and discharging will be low.
Character of battery Sulfation:
1. The capacity of battery will obliviously. Some may worse than 60%.
2. The density of electrolyte lower than normal range after charging complete. The voltage is also lower than normal range.
3. The voltage increase too quickly, peak voltage is high. The voltage also decreases quickly.
4. The gas is more than normal ones when charging. Electrolyte consuming is quick and need to re-supply pure water.
5. The appearance of electrode is not normal and much rough and hardness.
How Battery Desulfator Work?
From the analysis above, we could understand the major factor of battery failure is "sulfation". If we could naturalize the sulfation,
the battery could extend its lifespan. The sulfation will make the electrode accumulate the crystalline of PbSO4. The principle of
Desulfator is to produce a special electric pulse to eliminate the sulfation crystalline when charging. Let the electrode return its
original state. But more than that, Manida Desulfator could prevent the produce of PbSO4 accumulate on the electrode when charging.
By this way, the efficiency of charging, discharging, capacity of battery could return to new set status as possible. It will extend battery
lifespan to its designed target (10 years). We could feel its effect when start your vehicle after installing desulfator 10-14 days.
Application Scope of Battery Desulfator
The lead acid battery is a widely used electric capacitor. Almost every kind of transport vehicle could find them.
Since battery desulfator is working on lead acid battery, every kind of lead acid could use it for improvement lifespan.
How to choice battery desulfator¡H
There are two specifications to desulfator. 1. The voltage of your battery. In most automobile system, 12V is most popular.
Electrical bicycle use 12V or 24V battery. Some special system will use 48V battery. 2. The capacity of battery: the unit of
capacity is AH (Ampere-Hours). Automobile usually use 50-60AH battery. Electrical bicycle use 20-30AH battery.
Yacht or ship may use 200AH capacity. Please make sure your battery specification and choice proper desulfator.
Available types of Menida Desulfator are
1. 12V (type of 30AH and 200AH combined)
2. 24V 30AH
3. 24V 200AH
4. 48V 30AH
5. 48V 200AH

How much money can you save?
Average users in practical use, the lifespan of a lead acid battery is 18~24 months. However, only a few people know the fact
that the designed lifespan of a battery is 10 years. Why a huge difference in design and practices? The answer is "sulfation".
The ordinary maintain can't eliminate the sulfation. And this factor is hugely influence the lifespan of battery. It is reasonable for
at least 5 years lifespan if you install Desulfator to a new battery. (The battery still need necessary maintain for supply electrolyte.
Install in proper environment and proper usage.)
A 50~60AH lead acid battery cost USD 150.
Without desulfator. Five years need 3 batteries.
With desulfator. Five years for 1 battery
The money you can save!!
you use 100AH lead acid battery, one battery costs USD 500.
Five years, you can save USD 970.
1. Use desulfator can extend lifespan of battery. Also can save your time, money, manpower by lowering frequency of
battery changes. Suppose, you can't re-start your automobile in driving on the road. It will be danger your safety.
2. The Lead and sulfuric acid are heavy pollution material to environment. Lowering the quantity of failure battery can also
contribute to the earth environment.

Q1: Is it helpful to extend other automobile electric device if I install battery desulfator?
A: Yes, by indirect influence. The desulfator can make the battery provide a stable power to all electrical devices. The device
can work normally. This will help the lifespan of electric devices.
Q2: The voltage of battery can keep in normal range if I install desulfator in battery.
A: Yes. Desulfator can repair the battery electrode back to its original status. Suppose the battery capacity is 100% in its new
installation. After use for period, the capacity will lower to 90% or 80%. As time goes by, it will lower and lower when more sulfation
crystalline attached to battery electrode. Desulfator is helpful for battery providing stable voltage and current.
Q3: What is lifespan of a battery if installed with desulfator?
A: The designed lifespan of a battery is 10 years. If you install the desulfator to a new battery, it could extent the lifespan as long as
possible to designed lifespan. But if you install on a used battery, It may have other problem such as the electrode damaged, the
electrolyte density is not enough. The extent lifespan will be reduced compare to a new one.
Q4: How long will desulfator show its effect?
A: It depends on the status of your battery. Usually two to four weeks will make you feel difference.
Q5: If unload a battery from a automobile, will it continue produce sulfation?
A: Yes, a battery will continue produce sulfation crystalline even if not at work.
The sulfation of a battery is naturally produced by battery itself.
Q6: If the desulfator improved a battery's efficiency, can I install this desulfator to other battery?
A: Sulfation is continuing produced when battery in use. If you removed desulfator, the battery will start accumulate the sulfation
crystalline more rapidly.
Q7: Is it helpful for electrolyte density?
A: Yes. The density means the concentration of sulfuric acid in whole liquor. The sulfation will make sulfuric acid became PbSO4 particle.
The desulfator will return PbSO4 particle to sulfuric acid electrolyte.
Q8: What is temperature range for desulfator working?
Q9: Is desulfator waterproof?
A: It can't sink or partly sink in the water. But if the air is with high moisture or salinity, it could work normally. It is designed for ship batteries too.
Q10: What is the power source of desulfator?
A: The battery it linked will provide necessary power. No extra power needed. The red led will light up when working. The power consumption
is very small. Don't worry about power consumption of battery.
Q11: Is there any difference for menida desulfator to other similar products?
A: Other products usually work on the de-sulfation crystalline when charging. More than that, this one can prevent the sulfation effect when discharging.
Q12: Where are the remains when eliminating sulfation?
A: The desulfulator crash the sulfation crystalline into small particle. The small particle could easier react in the chemical reaction process.
So the Sulfation crystalline finally will return to sulfuric acid electrolyte.
